Benefits of technology

The invention is a system that can detect if a passenger in a vehicle is wearing a seatbelt and estimate the degree of damage to the passenger caused by an accident. This way, the system can accurately determine the criticality of the situation and quickly notify the appropriate authorities. Ultimately, the system ensures that all passengers are properly protected and helps reduce the likelihood of injury during a vehicle accident.

Problems solved by technology

However, there has been no technology for estimating the degree of damage to an occupant based on whether or not the occupant is wearing a seatbelt and determining the criticality (level of urgency) of the call, when an emergency call is made to a rescue center in the event of a vehicular accident or the like.
Even in the above-described related art, whether or not the seatbelt is worn is not considered when estimating the degree of damage to the occupant.

first embodiment

[0022]A vehicle emergency call apparatus 1 according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 3.

[0023]As shown in FIG. 1, the vehicle emergency call apparatus 1 according to the present embodiment is mounted in a vehicle 8. The vehicle 8 is provided with a plurality of acceleration sensors 2a, 2b, 2c, 2d, 2e, 2f, and 2g (each correspond to an impact amount detector equivalent to impact amount detecting means). The acceleration sensors 2a, 2b, 2c, 2d, 2e, 2f, and 2g are hereinafter referred to as acceleration sensors 2 when referred to collectively. The acceleration sensors 2 may be, for example, a capacitance-type acceleration sensor, a piezo resistance-type acceleration sensor, or a heat detection-type acceleration sensor.

[0024]The pair of acceleration sensors 2a and 2b are respectively provided in the left and right areas of a front end portion of the vehicle 8. In addition, the pair of acceleration sensors 2c and 2d are respect...

second embodiment

[0058]Next, the vehicle emergency call apparatus 1 according to a second embodiment will be described with reference to FIG. 4 to FIG. 6.

[0059]Here, only the differences between the first embodiment and the second embodiment will be described. Configurations in FIG. 4 that are the same as those in FIG. 1 are given the same reference numbers. In addition, although not shown in FIG. 4, the vehicle 8 according to the present embodiment is also provided with the acceleration sensors 2 and the occupant detection sensors 5 that are similar to those according to the first embodiment. The acceleration sensors 2 and the occupant detection sensors 5 are mounted in the same positions as those according to the first embodiment.

[0060]As shown in FIG. 4, according to the present embodiment, a collision position of the vehicle 8 (a position of the vehicle 8 at which impact is applied from outside of the vehicle 8) is detected based on the detection values from the acceleration sensors 2 during an ...

third embodiment

[0076]Next, the vehicle emergency call apparatus 1 according to a third embodiment will be described with reference to FIG. 7. Here, only the differences between the first embodiment and the third embodiment will be described. According to the present embodiment, the degree of damage to an occupant is determined so as to be classified into three levels: “high criticality”, “medium criticality”, and “low criticality”.

[0077]First, the airbag controller 3 determines, through the acceleration sensors 2, the magnitude of the impact applied to the vehicle 8 from outside of the vehicle 8 (step S701). Next, in a manner similar to that according to the first embodiment, the airbag controller 3 performs the processes at steps S702, 5703, and S704. Then, the airbag controller 3 proceeds to step S705 or S706.

[0078]When determined that the impact value of the impact applied to the vehicle 8 is lower than the threshold IMS2 at step S705, the airbag controller 3 proceeds to step S708. At step S708...

Abstract

In a vehicle emergency call apparatus, a call determining unit determines whether or not a degree of damage to at least one occupant seated in at least one vehicle seat is a predetermined degree required for an emergency call to be made, based on a detected impact magnitude applied to a vehicle and a predetermined impact magnitude. The call determining unit sets the predetermined impact magnitude to a first impact magnitude when a belt-wearing detector detects that at least one occupant seated in the at least one vehicle seat does not wear the seatbelt, and sets the predetermined impact magnitude to a second impact magnitude when the belt-wearing detector detects that the at least one occupant seated in the at least one vehicle seat wears the seatbelt. The first impact magnitude is set to be smaller than the second impact magnitude.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application is based on and claims the benefit of priority from Japanese Patent Application No. 2013-253136, filed Dec. 6, 2013, the disclosure of which is incorporated herein in its entirety by reference.BACKGROUND[0002]1. Technical Field[0003]The present invention relates to a vehicle emergency call apparatus that makes an emergency call during an emergency, such as a vehicular accident.[0004]2. Related Art[0005]There is a related art that relates to a vehicle emergency call apparatus (refer to, for example, JP-A-2007-538297). In the event of a vehicular accident, the vehicle emergency call apparatus estimates the damage to occupants based on the acceleration of the vehicle. The vehicle emergency call apparatus then transmits information related to the damage to the occupants to a rescue center for emergency medical treatment. In the related art, the seats in the vehicle are provided with seat mats. The seat mat detects whether or n...
